Pre-shading Tutorial

Post  Parabat on Tue Aug 27 2013, 16:09

I will do my best to explain the technique of pre-shading. It is done to accentuate the panels, particularly of aircraft, and is an effective way of helping to portray a weathered aircraft.
It is easy to perform and if you overdo the pre-shading, it can always be covered up.

Start with a primed model. Make sure the surface is clean and free of oils from fingers.

Spray your choice of a dark colour (eg black or tank grey) along the panel lines and especially into recesses like small intakes and you can even paint an entire small panel black if you want.
A point to note, is that if you are doing a really weathered example, you can even do some panels with white to really get some tonal variations.


Once the panel lines have been done and are dry, you can then start spray your surface colour. The underlying dark colour will now show through. You can reduce the stark effect of the underlying dark colour by increasing the layers you spray over it, remembering to not spray so much that you completely overspray the pre-shading.


Here you can see the result of the pre-shading. This was a black pre-shade, covered by Light Ghost Grey. I wanted it to appear quite prominent, so it only received two layers of spray.


Trivia:

You can 'reverse' pre-shade, by what is known as post-shading. This essentially is an overspray of the panel lines with your surface colour darkened with one or two drops of black to privide the contrast. This is more precise and requires a steady hand and fine setting on the airbrush, which is why I choose to pre-shade.
Some people also lighten the surface colour with a few drops of white and then spray in the centre of the panels outwards in order to create the faded look. This is somewhat a matter of taste, but can look effective.

Hi Josh,

Definitely. Get the black spray into the recesses and along joins/seams/panel edges and it'll have the same effect when you overspray, bringing greater 'depth' to vehicle body. You can really have fun with the pre-shading and use a combination of dark and light to create a great effect.
